This is a vintage souvenir mug likely from the 1970s to early 1980s, featuring a San Francisco cable car illustration and the word “California.” The style—especially the thick ceramic body, squared-off handle, brown/orange gradient banding, and printed decal graphic—matches the design trends of American souvenirware from that era. The fine crazing (crackling in the glaze) on the surface is common for older ceramics and adds to the vintage appeal.
